House Extensions Across Glasgow & Central Scotland
MKS Construction are specialists in house extensions across Glasgow, Kirkintilloch, East Dunbartonshire and Scotland's Central Belt. Whether you need extra living space, a home office, or a complete ground-floor transformation, we manage the full build from foundations to finishing.
Single-Storey Extensions
A single-storey extension is one of the most popular ways to add space to your home. We build rear extensions, side-return extensions, and wraparound extensions to suit your property layout and budget.
Common uses:
Open-plan kitchen and living areas
Garden rooms and home offices
Dining rooms and utility spaces
Downstairs bedrooms and wet rooms
Our team handles all groundworks, blockwork, roofing, plumbing, electrics and internal fit-out — so you deal with one contractor from start to finish.

Double-Storey Extensions
If you need significant space, a double-storey extension gives you two floors of new living area for less per square metre than two separate single-storey builds. Ideal for growing families who need both living space downstairs and bedrooms upstairs.
We specialise in connecting new builds to existing roof structures, including trussed and traditional cut roofs — ensuring structural integrity and a seamless finish between old and new.
Double-storey extensions often form part of a wider property renovation — we can manage the full scope from structural work through to kitchen and bathroom fit-out.
Loft Conversions
Make use of your existing roof space without extending the footprint of your home. Loft conversions are a cost-effective way to add a bedroom, office, or playroom.
We handle all aspects including structural steelwork, dormer construction, Velux windows, insulation, electrics, plumbing, and fire regulation compliance.
Conservatories & Garden Rooms
From traditional conservatories to fully insulated garden rooms suitable for year-round use, we design and build spaces that complement your existing home.
